Three Thousand Years of Ice

Physicist Shen Yan sealed his wife Su Wan into a freezing chamber at minus 196 degrees Celsius, lengthening time a million times. She stayed awake in the ice for three thousand years, carving her obsession with her fingernails; he watched outside the cabin for three thousand years, and eventually turned into data and seeped into the bulkhead to accompany him. After thawing, their brains were fused together, but they chose to separate, become ordinary people, and die peacefully together.
